Questions to Ask in a DevOps Engineer Interview

The interview is going well, then the hiring manager asks, "Do you have any questions for us?" Your mind goes blank, and you ask something generic about company culture that you could have read on their careers page.

That moment matters more than most candidates think. In DevOps, the questions you ask show whether you have actually run systems under pressure or just read about them. Interviewers notice the difference immediately.

Here are 12 questions worth asking, grouped by what each one reveals. Ask three or four, not all twelve. Pick the ones that match what you care about.

Questions that reveal the team reality#

These tell you how the team actually works day to day, not how the job description says it works.

How does a typical incident get handled, from alert to postmortem?

This is the single best question you can ask in a DevOps interview. It tells you whether they run blameless postmortems or whether incidents end with someone getting yelled at. Listen for whether they mention timelines, follow-up actions, and whether fixes actually get shipped.

Who owns the pipelines and infrastructure code right now?

Some teams have a dedicated platform group. Others have one person who set everything up three years ago and is now the bottleneck. Their answer shows you how work is shared and where you would fit.

What did the last person in this role do that worked well, and what did they leave unfinished?

This one is direct, and it lands. You learn what success looked like and what mess you are inheriting. If they cannot answer, that is data too.

How much of the week goes to planned work versus unplanned work?

Every team has some fire-fighting. The split matters. If they say it is fifty-fifty, ask what is being done about that.

Questions that reveal priorities#

These show you what the company actually values, which is often different from what the website says.

What are the platform or infrastructure goals for the next two quarters?

You want a concrete answer here: a migration, a reliability target, a cost project, something. Vague answers about "scaling the platform" mean the roadmap is not clear yet.

How do you decide what to build in-house versus buy?

This reveals maturity. Teams that buy the boring stuff and build the differentiating stuff tend to be calmer places to work. Teams that build everything themselves are usually drowning.

What is the current stance on AI tooling in engineering workflows?

By 2026 most teams have some position on this, whether it is code assistants, automated runbooks, or anomaly detection. Ask openly and without judgment. You want to know if they ban it, ignore it, or use it with guardrails.

Questions that reveal success criteria#

These tell you how your work will be judged in the first year.

What would make you say, six months from now, that hiring me was the right call?

Ask this near the end. It forces a specific answer and gives you a target to write into your own notes. Managers who have thought about onboarding answer this quickly.

Which metrics does the platform team report upward?

DORA metrics, availability numbers, cloud spend, ticket resolution time. Whatever they name, you learn what gets attention when leadership looks. If they report nothing, expect priorities to shift with whoever shouts loudest.

How are DevOps engineers evaluated in performance reviews?

Some companies reward shipping features. Others reward reliability and cost control. Find out before you accept, because you will spend your year optimizing for whatever they measure.

Questions that reveal risk#

These are the uncomfortable ones. Ask them politely and you will learn more than from any other question.

What is the biggest risk in the infrastructure right now?

Every honest engineer has an answer. Aging Kubernetes clusters, single-region deployments, no disaster recovery testing, a database nobody wants to touch. Their candor level tells you about the culture.

What would break first if traffic doubled overnight?

This is a classic reliability question turned around and aimed at them. Their answer shows whether anyone has actually thought about capacity, and how well they know their own system.

Questions to avoid#

Some questions hurt you even when they are perfectly reasonable in other contexts.

• "What does your company do?" Read their site first. Always.
• "How quickly can I get promoted?" Ask about growth paths instead, and ask it later in the process.
• "Is remote work allowed?" Ask the recruiter early, not the hiring manager at the end.
• "What is the salary?" Save it for the recruiter screen or the offer stage. Do not open with it.
• Anything you could have answered with two minutes of research. Interviewers notice laziness.

How to read the answers#

The words matter less than the specifics. A good answer includes a concrete example, a name for a real system, or a number. A bad answer is all adjectives.

Watch for hedging on the incident question. If nobody can describe their postmortem process, either they are very early in building one or they do not run one. Both are worth knowing.

Notice who answers. If the hiring manager deflects every technical question to the engineer beside them, that tells you about their involvement. If the engineer never speaks, ask them directly what their week looks like.

Worked example: turning their answer into your follow-up

Suppose you ask about incidents and they say, "We use PagerDuty, and we have a weekly review."

Weak follow-up: "That sounds great."

Strong follow-up: "When the review turns up an action item, who tracks it to completion? I have been on teams where those items sat in a backlog for months."

That follow-up shows you have lived through the failure mode. It also forces a real answer. Do this two or three times in an interview and you will read as senior, no matter your years of experience.

A short checklist before you walk in#

• Read the job description twice and mark three things you want explained.
• Look up their tech stack on their engineering blog or job posts.
• Prepare four questions and rank them. You may only get time for two.
• Write your questions down and bring the notebook. Nobody minds.
• Decide in advance which answer would be a dealbreaker for you.

FAQ#

How many questions should I ask in a DevOps interview?

Aim for three to four across the whole process, and two or three in any single session. If they say they have answered everything, believe them and stop. Asking questions you do not care about just to fill time reads as nervous.

Should I ask the same questions to the recruiter and the hiring manager?

No. Save technical and team questions for the hiring manager or engineers. Use the recruiter screen for logistics, comp range, and process timeline. Asking a recruiter about postmortem culture wastes both your time.

Is it bad to ask about on-call in the first interview?

It is fine, and most engineers respect it. Frame it as wanting to understand the operational load rather than as trying to avoid it. Something like, "How is on-call distributed, and how often does a page wake someone up?" works well.

What if the interviewer gives a vague or defensive answer?

Ask once more with a concrete frame, for example, "In the last month, what took up most of the team's time?" If you still get nothing, take that as your answer. Vague teams stay vague after you join.

Do these questions work for platform engineering roles too?

Yes, most of them transfer directly. Platform roles care more about internal customers, so add a question about who the platform serves and how they collect feedback from the teams using it. That swap keeps the same depth while matching the role.
